Further evidence of the way American movies have gotten more buttoned-down since the 80s. After all, THX 1138 was a PG film on its first release, but an R in 2004 - for the exact same nudity!
Somebody making a Star Wars type film today probably wouldn’t even consider having bare breasts on screen. For which state of affairs the huge success of SW itself - and its co-option by the US political right-wing - bears a large share of blame.
